Can Augmentin (amoxicillin/clavulanate) tablets be split or cut to take with food?

Can Augmentin Tablets Be Split or Cut?

The answer depends entirely on the formulation: Augmentin tablets (immediate-release) can generally be split if they are scored, but extended-release formulations should never be cut or crushed, and oral suspensions cannot be "divided" as they are already in liquid form.

Formulation-Specific Guidance

Immediate-Release Tablets

• Standard Augmentin tablets may be split if they have a score line, though this is not explicitly addressed in the FDA labeling
• The critical consideration is maintaining accurate dosing of both the amoxicillin and clavulanate components
• Splitting unscored tablets risks uneven distribution of the active ingredients

Extended-Release Tablets

• Never split, cut, or crush extended-release Augmentin formulations 1
• The extended-release mechanism depends on intact tablet architecture
• Disrupting the tablet structure causes immediate release of the entire dose, eliminating the pharmacokinetic benefits and potentially increasing adverse effects
• Research demonstrates that gastric residence time and intragastric positioning critically affect bioavailability of both components in ER formulations 1

Oral Suspension

• The question about "dividing" suspension is moot—it's already a liquid formulation
• Augmentin suspension should be taken at the start of a meal to minimize gastrointestinal intolerance 2
• Absorption of clavulanate potassium is enhanced when administered at meal initiation 2

Administration with Food

Regardless of formulation integrity:

• Always administer Augmentin at the start of a meal 2
• Food significantly affects bioavailability, particularly for amoxicillin (AUC increases from 1854 to 2452-2605 μg·min/mL when taken with food vs. fasting) 1
• High-fat meals can decrease clavulanic acid exposure by approximately 40% when taken after eating rather than at meal start 3

Common Pitfalls

• Do not confuse different Augmentin formulations—the 200 mg/28.5 mg/5 mL and 400 mg/57 mg/5 mL suspensions are NOT interchangeable with ES-600 formulation 2
• Splitting tablets without proper scoring may result in inaccurate dosing of the clavulanate component, which is present in lower concentrations
• Taking medication after a meal rather than at the start reduces clavulanic acid bioavailability 1, 3
